Benefits of technology

[0007]The object of the present invention is therefore to make available a high-temperature patch plug for connection lines, especially for connecting heating elements and / or thermocouples, as well as temperature sensors, which is compact and can be manufactured in a favorable manner.

Problems solved by technology

However, such patch plugs do not, as a rule, meet the special requirements that are associated with high-temperature applications, in which the plugs are exposed to a thermal load of 120° C. and higher.
This problem becomes even more acute as the desired designs become ever more compact.
The drawback of this embodiment is that the manufacture of a plug-in connection is associated with a relatively great effort.
Furthermore, the space requirement is relatively high, especially for multipole high-temperature plug-in connections, which are based in these plugs.

Embodiment Construction

[0028]Referring to the drawings in particular, identical reference numbers are used for identical components of the same exemplary embodiments in all figures, unless mentioned otherwise.

[0029]FIG. 1a shows the view of a single-pole exemplary embodiment of a high-temperature patch plug 50, viewed against the plugging direction. A housing 51 with a detent 52 is recognized. The plug-side boundary surface of housing 51 is passed through by a passage opening 57, which is limited by a double circle because of a wall 67 beveled as an insertion aid, and by a duct opening 65. Lines B-B and C-C represent section lines, which illustrate the perspective of the views in FIGS. 2 and 3, from which the design of the high-temperature patch plug 50 appears even more clearly.

[0030]FIG. 1b shows the same view of a two-pole high-temperature patch plug. A housing 81 with a detent 82 is recognized. The plug-side boundary surface of housing 81 is passed through in this embodiment by two passage openings 83...

Abstract

A high-temperature patch plug (50) for one or more connection lines (60), especially for connecting electric supply and / or signal lines to heating elements and / or thermocouples or temperature sensors. The patch plug (50) has one or more poles each with a contact element (64) connected to an inner conductor (61) of a connection line (60), and with a one-piece, insulating housing (51), which surrounds an interior (59), in which at least the at least one contact element (64) is accommodated at least partially. The housing (51) has at least one insertion opening (63) on the side facing away from the plugging side and a passage opening (57), which is connected to the insertion opening via the interior (59) of housing (51) for each pole on the side facing the plugging side. The contact element (64) is locked in the housing (51) for each pole at a locking step (53) arranged in the interior of the housing such that a motion of the contact element (64) against the plugging direction is limited by the locking, wherein said locking step (53) is formed by an irreversible deformation of housing.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority under 35 U.S.C. §119 of German Patent Application DE 20 2009 011 857.6 filed Sep. 2, 2009, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention pertains to a high-temperature patch plug for connection lines, as it is used especially for connecting electric supply and / or signal lines to heating elements and / or thermocouples or temperature sensors.BACKGROUND OF THE INVENTION[0003]A plurality of patch plugs, in which electric connection lines are connected to an insulating, one-piece housing with a contact element accommodated in said housing, are already known. The housings are manufactured, as a rule, from a plastic, injection molding processes being used in many cases.[0004]However, such patch plugs do not, as a rule, meet the special requirements that are associated with high-temperature applications, in which the plugs are expo...
